SHADE 0B REFLECTOR ATTACHMENT.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application filed. December 8, 1909. Serial No. 531,953.

To all whom it may concern:

Be it known that I, HENRY DOLIER, J r., a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Shade or Reflector Attachments, of which the following is a specification.

My invention relates to an attachment for a shade or reflector, and particularly to means for attaching a shade orrefiector to an electric incandescent lamp.

While an electric incandescent lamp is giving light it also gives ofl considerable heat which very considerably raises the temperature of a shade or reflector and its at tachment, unless some ventilating means be provided for allowing the heated air to escape.

It is the object of my invention to provide a shade or reflector attachment which shall also provide ventilation to keep the temperature of the shade or reflector, the attachment, and, in fact, all associated parts, reasonably low, and at the same time secure such ventilation without the escape of light in undesired directions.

For an illustration of one of the forms my invention may take, reference is to be had to the accompanying drawing, in which:

Figure 1 is a vertical elevational view of a lamp socket and an electric lamp held thereby, and a shade or reflector and its attachment, the shade or reflector and the at-.

tachment being shown in vertical sectional view. Fig. 2 is a top plan view of a shade or reflector with its extension. Fig. 3 is a fragmentary sectional view through a shade or reflector having no separate extension member, but provided with a feature of my invention.

Referring to Fig. 1, S is an electric incandescent lamp socket in which is secured in the usual manner an electric incandescent lamp L, the current being supplied through the electrical conductors c, 0. Upon the socket Sthere is provided a bead b with which registers the bead a of a resilient ring member 7' which is circumferentially discontinuous and which may be sprung over the socket, so that the beads a and b register with each other. At its lower portion the ring member 7 is provided with a bead cl and a flange 6 between which is formed a groove in which there is held the inturned substantially horizontal flange f on the eX- tension member 9. Securedto or supported by the extension member 9 is the shade or reflector proper R, the shade or reflector R, the member 9, and the ring 1 being preferably made of sheet metal. In the substantially horizontal portion f are provided a plurality of perforations it. Through these perforations it may escape the air from within the reflector R and from around the lamp L, thus maintaining the parts at reasonably low temperature. And inasmuch as the perforations are in the substantially horizontal portion f the light escaping through such perforations is directed upwardly and is not noticed by an observer looking directly at the reflector while the lamp L is burning. By this arrangement, therefore, it is possible to satisfactorily ventilate the apparatus and yet allow no light to be visible above the reflector or shade R.

In Fig. 3 a fragment of a shade or re flector B only is shown, no separate extension member being provided. The shade or reflector R has formed thereon a boss or projection raised from the body of the shade or reflector, and such boss is provided with the horizontal flange or lip f, the latter again provided with perforations h which allow ventilation, but cause the escaping light to be invisible in undesired directions.

From the foregoing description it is apparent that I provide the ventilation perforations in a horizontal inwardly turned lip or flange upon a boss or extension member, and both boss and extension member are hereinafter referred to in the claims as an extension.

The inturned lip or flange is integral with the extension and lies in a plane at right angles to or normal to the axis of the lamp socket, thus preventing escape of light through the ventilating perforations in undesired directions, and serving also as a ready means for attachment to the lamp socket.

What I claim is:

l. The combination with a lamp socket casing, of a shade or reflector, an extension on said shade or reflector, an inturned lip or flange on said extension at one end thereof and integral therewith, said lip or flange being normal to the axis of said socket casing and having an aperture therein, and

means engaging in said aperture and engaging said lamp socket casing, said lip or flange having ventilating perforations outside of said aperture.

2. The combination with a lamp socket, of a shade or reflector unit, and means for attaching said shade orreflector unit to said socket comprising an extension on said shade or reflector unit, an inturned lip or flange at one end of said extension and integral therewith, said lip or flange being normal to the axis of said socket and having an aperture therein, and means supported by said socket engaging in said aperture in said lip or flange, said lip or flange having ventilating perforations outside of said supporting means.

3. The combination with a lamp socket, of a shade or reflector unit, and means for sup porting said shade or reflector unit upon said socket comprising an extension on said shade or reflector unit, an inturned lip or flange upon one end of said extension and integral therewith, said lip or flange being inturned lip or flange upon one end of said extension and integral therewith, said lip or flange being normal to the axis of said extension and having ventilating perforations.

5. As an article of manufacture, a shade or reflector havingan extension, an inturned lip or flange on one end of saidextension and integral therewith, said lip orflange having an aperture adapted to receive sup? porting means, and said lip or flange having ventilating perforations outside of said aperture. v
